Photoelectric anti-collision device of cranes

Abstract

The invention discloses a photoelectric anti-collision device of cranes. The photoelectric anti-collision device comprises a light projecting device and a light receiving device which are respectively mounted on two cranes, wherein the light projecting device comprises a power source I and a light projector; the light receiving device comprises a light receptor, an amplifier, a relay, a waveform reshaping loop and a power source II; the power source II is sequentially connected with the amplifier, the waveform reshaping loop and the light receptor; the relay is connected with the amplifier; a buzzer is connected on the relay; and the light projected by the light projector is received by the light receptor, and is converted into a digital signal through the amplifier and the relay to control the buzzer to send out alarm. According to the invention, the photoelectric anti-collision device of cranes is used for preventing a lifting device from colliding during the operation process and guaranteeing safe operation; and the structure is simple, the design is reasonable, the application range is wide, the safety and reliability of operation of cranes can be improved, collision is prevented when workers operate the cranes, and the operation accident is reduced.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a photoelectric anti-collision device for cranes. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and transports heavy objects horizontally within a certain range. The working characteristics of lifting equipment are intermittent movements, that is, the actions of taking, moving, and unloading in a working cycle. The corresponding mechanism works alternately. The development and use of cranes in the market are becoming more and more extensive. In the existing application environment of cranes, multiple cranes are often used at the same time. They will collide with each other, causing crane damage and safety accidents. Contents of the invention [0003] In order to overcome the above defects, the present invention provides an anti-collision system for cranes, quay cranes, rail cranes, portal cranes and other lifting equipme...
